Additional Details

The TLE42364G provides a stable output voltage even when the input voltage fluctuates. This is especially useful in automotive applications where the battery voltage can vary significantly. The overvoltage protection will shut down the output voltage if the input voltage exceeds a certain limit. The short circuit protection will limit the output current in case of a short circuit. The over temperature protection will shut down the output voltage if the junction temperature exceeds a certain limit. The IC also has a reverse polarity protection that prevents damage to the IC if the input voltage is accidentally reversed. It is designed to meet the stringent requirements of automotive applications. The TLE42364G is available in a small PG-DSO-8 package. All the protection features improve the reliability of the application. It is designed for safety relevant applications.
